ABSTRACT

A spare tire cover is constituted by a fix-up plate  4  having a plurality of fixing holes  40   a,    40   b,  a rear cover  2  to which the fix-up plate  4  including a slide fastener  3  is mounted, and a top cover in which a plurality of projections  10   a,    10   b  are provided in an inner surface. The fix-up plate  4  is mounted and fixed to an inner side surface of the top cover  1  on the basis of a fitting connection between the fixing holes  40   a,    40   b  and the projection holes  10   a,    10   b.  The slide fastener  3  and a seamed portion of the rear cover  2  are wound up and held in the inner side of the top cover  1  by the fix-up plate  4  so as to integrally attach the rear cover  2  to the top cover  1.  Accordingly, it is possible to omit a sewing of the other members with respect to a largely bulky hard top cover and it is possible to construct on the basis of a simple operation. Further, it is possible to integrally attach the rear cover to the top cover on the basis of a strong structure, and it is possible to construct a spare tire which can be easily attached and detached and has a good appearance.

TECHNICAL FIELD

The present invention relates to an improvement of a spare tire cover which covers a spare tire mounted to a rear portion of the like of a vehicle body.

BACKGROUND ART

In general, in a type of motor vehicle such as an off-road car or the like shown in FIG. 13, a base table having a plurality of stud bolts protruded therefrom is provided in a rear portion of a vehicle body B, and a spare tire which is attached by nuts by inserting the stud bolts to bolt holes in a tire wheel is covered by a tire cover C, whereby the spare tire is mounted to the rear portion of the vehicle body B.

In conventional, as the spare tire cover, there has been proposed a structure which is constituted by a cup-shaped hard top cover receiving from one side surface of the tire up to a tread portion and a flexible rear cover provided with a rubber band elastically drawing a center opening, formed in a donut shape and covering another side surface of the tire, setting the rear cover in an outer periphery of the top cover by an outer peripheral edge so as to integrally attach to the top cover (Japanese Utility Model Application Laid-Open No. 4-60785).

In the spare tire cover, since the rear cover is set in the hard top cover while handling the top cover which is largely bulky together therewith, a significantly lot of man hour is required for setting, and a seam of the rear cover is exposed to an exterior portion. Further, since it is necessary to execute an attaching and detaching operation while drawing out and expanding the center opening of the rear cover by the rubber band, a lot of man hour is required for this attaching and detaching operation.

In order to make it easy to attach and detach the spare tire cover, there is proposed a spare tire cover structured such that respective zipper teeth tapes are respectively set in outer peripheral edges of a top cover and a rear cover, a slide fastener is provided, and a rubber molding covering a seam in a side of the top cover is set in so as to overlap with a side of the rear cover (Japanese Patent Application Laid-Open No. 9-71270).

In the spare tire cover, since at least one of the zipper teeth tapes is set in the hard top cover even when the slide fastener is provided in all around the periphery or in a main portion except a part thereof, it is necessary to execute the sewing of the zipper teeth tape caused by handling the largely bulky hard top cover together, so that a lot of man hour is required in the same manner as the preceding prior art.

A main object of the present invention is to provide a spare tire cover which can be constructed on the basis of a simple operation with omitting a sawing operation of the other members with respect to a largely bulky hard top cover, can integrally attach a rear cover to the top cover on the basis of a strong structure and has a good appearance.

In addition, another object of the present invention is to provide a spare tire cover which can prevent an abnormal noise or the like from being generated due to a friction between the top cover and the tire, and can be further easily attached and detached.

MODE FOR CARRYING OUT THE INVENTION

A description will be given of an embodiment with reference to FIGS. 1 to 12. An illustrated embodiment is constituted by a cup-shaped hard top cover 1 receiving a tire T from one side surface thereof to a tread portion t₁, and a flexible rear cover 2 covering another side surface of the tire T by a defined width surface from an outer peripheral edge of the top cover 1 to a center opening, and is applied to a structure in which a slide fastener 3 is provided in a main portion between the top cover 1 and the rear cover 2, as shown in FIG. 1. In this case, “upper and lower” and “right and left” in the description are given on the basis of a mounting attitude of the tire T.

The top cover 1 is formed by a disc-like face portion 1 a, a circular frame-like flange portion 1 b and a rounded corner portion 1 c continuously connected to the flange portion 1 b from the face portion 1 a so that a whole of the cover forms a cup shape, as shown in FIG. 2. The whole of the cover is formed by a resin material such as a hard polypropylene or the like which can be welded by an ultrasonic wave by welding and bonding projections mentioned below.

A plurality of cylindrical projections 10 a and 10 b protruding from an inner surface to an inner side in a substantially center direction are provided in an inner side from an outer peripheral edge of the flange portion 1 b along a circumferential direction with a predetermined interval, in the top cover 1, as shown in FIG. 3. The projections 10 a and 10 b are supported by ribs 11 a and 11 b continuously connecting the adjacent projections to each other so as to position a reinforcing and fix-up plate, and ribs 12 a and 12 b extending in an orthogonal direction in a rise base portion. Further, a plurality of ribs 13 a and 13 b which reinforce the corner portion 1 c from an inner surface side and fill up a gap with respect to a shoulder portion of the tire T are provided in a circumferential direction with a predetermined interval.

In addition, elastic pads 14 a and 14 b (refer to FIG. 1) made of an urethane foam or the like which receive a side wall portion t₂ of the tire T are respectively attached to portions near upper, lower, left and right corner portions 1 c on an inner surface of the face portion 1 a in the top cover 1. Further, as shown in FIG. 4, one drain hole 15 is provided in a center of a lower portion of the flame portion 1 b.

The rear cover 2 is formed by a flexible material such as a polyvinyl chloride leather or the like. This rear cover 2 is formed by cutting the flexible leather into one sheet having a predetermined shape or cutting into a center upper portion 2 a, left and right side portions 2 b and 2 c and left and right lower portions 2 d and 2 e in view of efficiency for shaping and cutting as shown in FIG. 5 and sewing them in a predetermined shape. The rear cover 2 is formed so as to form a defined width surface covering one side surface of the tire T in a wide surface having one width and continuously connecting to the left and right side portions 2 b and 2 c from the center upper portion 2 a, form in a narrow surface tapered toward the left and right lower portions 2 d and 2 e continuously connecting from the left and right side portions 2 b and 2 c, and be separated into left and right sections from centers of the lower portion 2 d and 2 e.

As the slide fastener 3, there is provided with a structure in which a plurality of zipper teeth are attached so as to be aligned with opposing edges of respective fabric tapes and a slider engaging or disengaging the zipper teeth is provided. The slide fastener 3 is structured such that two lanes 3 a and 3 b are mounted so as to extend to left and right side portions from center positions of the lower portions 2 d and 2 e except the center upper portion 2 a of the rear cover 2.

In addition to the respective portions in the structure mentioned above, a fix-up plate 4 is provided as shown in FIG. 6. The fix-up plate 4 is formed in a band plate shape in which a plurality of fixing holes 40 a and 40 b which are arranged in a longitudinal direction of a plate surface with a predetermined interval. Further, in order to weld and connect the projections in the top cover 1, it is formed by a resin material such as a polypropylene or the like which can be welded in accordance with an ultrasonic wave. In this case, the fixing holes 40 a and 40 b are formed in oblong holes so as to make it possible to easily position adjust a fitting with the projections in the top cover 1, except a round hole provided as a positioning reference.

The fix-up plate 4 is formed so that one line side is set to a seam allowance 41 and a thickness is relatively larger than that in a side in which the fixing holes 40 a and 40 b are provided. Further, ribs 42 and 43 having a high rise are provided along a longitudinal direction in both sides of the fixing holes 40 a and 40 b in the plate surface so as to prevent the welded projections from being in contact with the tire surface and commonly serve as a reinforcement, by sectioning one side with respect to the seam allowance 41 and protruding another side from one edge line.

The fix-up plate 4 may be formed in view of easiness for handling such as seaming or the like, for example, by separating into a plurality of sections 4 a and 4 b in correspondence to the respective portions constituting the rear cover 2, as shown in FIG. 7. In each of the joint portions, the plates can be connected and fixed to each other by providing with a receiving edge 45 in which a projection 44 is provided in a protruding manner in one plate portion 4 a and providing with a joint piece 47 in which a fitting hole 46 for the projection 44 is opened in another plate portion 4 b.

The fix-up plate 4 is mounted to the rear cover 2 so as to position the seam in the inner side by folding back the rear cover 2 from the seam after overlapping the outer peripheral edge of the center upper portion 2 a with the seam allowance 41 in a front surface side and sewing the outer peripheral edge of the center upper portion 2 a to the seam allowance 41 of the fix-up plate 4, in the center upper portion 2 a of the rear cover 2, as shown in FIG. 8.

Further, as shown in FIG. 9, in the lower portion 2 d of the rear cover 2 provided with the slide fastener 3, the fix-up plate 4 is mounted to the rear cover 2 by overlapping one zipper teeth tape 30 in the front surface side, sewing one zipper teeth tape 30 to the seam allowance 41 of the fix-up plate 4 and thereafter folding back, on the contrary, overlapping another zipper teeth tape 31 with the lower portion 2 d of the rear cover 2 in the front surface side and sewing.

The fix-up plate 4 is assembled and arranged in the inner surface side from the outer peripheral edge of the top cover 1 by mounting the fix-up plate 4 to the rear cover and fitting the fixing hole 40 a of the fix-up plate 4 to the projection 10 a of the top cover 1 as shown in FIG. 10 a. Since the fix-up plate 4 is assembled and the projection 10 a is deformed and firmly fixed as a welded projection 10 a′ in accordance with an ultrasonic wave as shown in FIG. 10 b, the fix-up plate 4 is firmly bonded and fixed along the inner surface of the top cover 1. Further, the rear cover 2 is integrally attached to the top cover 1 by winding up and holding the slide fastener 3 and the seamed portion of the rear cover 2 in the inner side from the outer peripheral edge of the top cover 1 by the fix-up plate 4.

In the spare tire cover structured in the manner mentioned above, since the slide fastener 3 and the seamed portion of the rear cover 2 are bonded and fixed to the inner surface of the top cover 1 by the fix-up plate 4, it is possible to omit the sewing with respect to the largely bulky hard top cover 1 and it is possible to easily construct. Further, since the slide fastener 3 and the seamed portion of the rear cover 2 are wound up and held in the inner side from the outer peripheral edge of the top cover 1 by the fix-up plate 4, the seam is not exposed to the outer surface of the top cover 1 and it is possible to obtain the structure having a good appearance.

In addition, since the fix-up plate 4 which can be welded in accordance with the ultrasonic wave and is made of the same material is welded and bonded by the projections 10 a and 10 b of the top cover 1, and fix-up plate 4 is reinforced by two ribs 42 and 43 provided in the longitudinal direction, it is possible to integrally attach the rear cover 2 to the top cover 1 on the basis of the strong structure.

In the attaching state of the spare tire cover, since the elastic pads 14 a to 14 d (refer to FIG. 5) provided near the upper, lower, left and right corner portions 1 c on the inner surface of the face portion 1 a are interposed with respect to the side wall portion t₂ of the tire T, it is possible to prevent the abnormal noise from being generated due to the friction between the tire T and the top cover 1. Further, since the ribs 42 and 43 of the fix-up plate 4 rise up rather than the welded projection 10 a′, the welded projection 10 a′ is not exposed to the friction deformation given by the tire T.

Since the spare tire cover can be attached and detached in a state of opening the rear cover 2 by the slide fasteners 3 a and 3 b as shown in FIG. 11, it is possible to easily attach and detach the spare tire cover. In particular, since the lower portion side of the rear cover 2 forming the open port is formed in the tapered narrow surface except the extra width, as well as it is possible to further easily handle, it is not necessary to mount the surface fastener or the like stopping the extra width.

In the attaching state of the spare tire cover, it is possible to intend to prevent a shift opening of the slide fastener due to a wind pressure or the like, a burglar and the like by locking the pad lock 5 to a picking piece 32 (33) in the slide fasteners 3 a and 3 b as shown in FIG. 12. In this case, one side including the zipper teeth tape of the slide fastener 3 appears around the edge of the rear cover 2, however, since this is positioned in a side of the vehicle body panel in the attaching state of the whole of the cover and does not appear in the outer portion, no influence is given to the appearance.

The description is given of the embodiment mentioned above in the case that the slide fastener 3 is provided in the other portions than the center upper portion of the rear cover 2, however, the structure may be made such that the slide fastener is provided around all the periphery from the lower portion of the rear cover 2. In this case, the fix-up plate may be mounted to the rear cover via the slide fastener by sewing the fix-up plate with one zipper teeth tape all along the length and sewing another zipper teeth tape with all the periphery except the lower portion center of the rear cover.

The description is given of the embodiment mentioned above on the basis of the spare tire cover which is provided with the slide fastener and constructed so as to be freely attached and detached, however, the embodiment can be applied in the same manner to a spare tire cover in an aspect in which the rear cover is directly attached to the top cover by the fix-up plate.

In this case, the description is given of the case in which the top cover 1 and the fix-up plate 4 are formed by the resin material which can be welded in accordance with the ultrasonic wave, however, the other welding methods can be applied, and the top cover 1 and the fix-up plate 4 may be formed by a resin material to which the selected welding method can be applied.
